  • Patent number: 5749045
    Abstract: A method for handling alarm conditions from paging stations in a paging system is disclosed. The paging system includes a paging terminal, a plurality of paging stations, and a network manager. When a paging station has an alarm condition, the paging station forwards the alarm to the network manager, which in turn, compares the alarm with an alarm record for that paging station and determines whether or not that alarm is a higher priority than the previous alarms received from the paging station. If so, the network manager transmits a signal to the paging terminal to page the technician responsible for servicing that particular paging station. The technician is paged and dispatched to the paging station for service.

  • Patent number: 5717378
    Abstract: A security system having a communications link with a central control, including a local network responds: a) to central control when the central communications link is operational; and, b) to local control when the central communications link malfunctions. More specifically, the local network includes a plurality of receivers for detecting emergency communications, an alarm for issuing a perceptible warning and a local control. The local control notifies the central control when an emergency signal is detected and activates the alarm in response to direction from the central control. The local control also includes logic for directly activating the alarm when an emergency signal is detected and there is no response from central control. According to more specific features, the central control includes data for validating emergency signals and activates the alarm only after validation. The local control, on the other hand, activates the alarm without validation.

  • Patent number: 5661492
    Abstract: A population of locatable personal detection units (PDUs) (20) are worn by users. Any number of locators (14) are placed at known locations within an area (10) where the users tend to be. When an alarm event for an individual user occurs, a request signal is transmitted from the user's PDU (20). The request signal is received at several of the locators (14), each of which measure the power level of the request signal. A central computer (16) selects some of these locators (14) in response to the power level measurements. In sequence, the selected locators (14) transmit an interrogation signal to the PDU (20), the PDU (20) replies to the interrogation signal, and the locators (14) measure the duration transpiring between the interrogation and the reply. Based on the durations measured for at least three of the locators, the central computer (16) uses a multilateration process to localize the PDU (20).

  • Patent number: 5568121
    Abstract: A system for sensing information at a plurality remote, typically hazardous, locations and transmitting the sensed information to a main monitoring center. Remote portable "attendants" that take the place of a human safety monitor are carried by persons at the remote locations. The portable attendants produce an audible and/or visual warning to the operator at selected times. If the operator does not acknowledge the warning within a selected time, an alarm signal is sounded and is sent to the main central by radio for processing in a central processing unit (CPU). The CPU directs an appropriate safety response and may open a voice radio circuit between central operators and the remote monitor location. A switch is provided so that the remote operator can manually trigger the alarm.

  • Patent number: 5534851
    Abstract: An alarm system for notifying necessary medical and hospital personnel that a patient or the patient's life support equipment require immediate response without providing the alarm signal to the monitored patient or surrounding patients, to prevent patient trauma which may otherwise result from the sound of the alarm. The system includes an alarm signal generator that provides a coded pulse indication of the patient and equipment type. The coded signal is sent to a master control unit preferably located at a nurses' station. The master control unit then transmits the coded alarm signal simultaneously to the appropriate group of pagers having vibrational annunciators and a visual display that describes the patient location and equipment type. The patients monitor and equipment at bedside and the pagers have no audio alarm signals. The alarm signal can only be terminated manually by an interrupt switch at the bedside.

  • Patent number: 5382941
    Abstract: A vehicle alarm set signal level control that controls the volume of a car alarm and also the output level of the alarm setting or arming signal. The alarm volume is controlled by a frequency responsive circuit employing a silicon control rectifier in combination with a zener diode and a resistance that can be left in or removed from the circuit. Arming signal level control is comprised of a bypass circuit employing a transistor and a photo detector in combination with a potentiometer. The level of the output signal when setting the alarm is varied according to the amount of light available. In an optional embodiment for a car alarm using a low level signal both an arming signal setting signal level control and a visible output are used. The circuit employs a pulse rate controller providing an output through a protection circuit and a volume control to a piezoelectric tone generator.

  • Patent number: 5309144
    Abstract: A security system uses a base unit and a portable transceiver which cooperate to provide automatic monitoring of a secure perimeter. An intrusion sensor is employed to activate a transmitter for emitting a selected frequency wave energy challenge transmission upon the detection of an intruder either outside the perimeter or entering the perimeter. If the intruder has the portable transceiver present to receive the challenge transmission, it automatically emits a responsive wave energy signal as an acknowledgment. A base unit receiver detects the acknowledgment signal and prohibits alarm action. If no acknowledgment signal is received, then either a warning or an alarm is triggered at the base unit. The system does not require manual control. The several distinct wave energy signals can be chosen from among various available radio frequency electromagnetic, and audible or ultrasonic acoustic, waves.

  • Patent number: 5278539
    Abstract: An emergency alerting system for alerting or warning large numbers of people of the occurrence or threat of an emergency using available communications media. Multiple facilities are monitored for the occurrence of multiple alarm conditions. On the occurrence of such a condition radio or telephone contact is made with a Local Emergency Planning Committee (LEPC) and the LEPC is notified of the site and nature of the alarm condition. Using a predetermined listing or data bank the LEPC selects a number corresponding to the site and condition and transmits such number to an automated controller for a radio transmitter. The transmitter may be part of an existing radio paging system. The automated controller, on the basis of the number dialed in by the LEPC, transmits an appropriate Code Assignment Plan (Cap Code) signal. The Cap Code signal is the electronic signature of a preprogrammed Cap Code chip within individual radio receivers positioned at the sites of intended alarm recipients.

  • Patent number: 5266925
    Abstract: An electronic identification tag interrogation method is provided in which a portal transmits an interrogation signal which is received by an electronic identification tag within its field of range. The interrogation signal includes an address which requests a response from every tag having an address greater than or equal to the address of the signal. If more than one reply is received by the portal, the interrogation address is bisected and the interrogation signal is retransmitted. The interrogation address is successively bisected until a single response is isolated. When a single response is isolated, communication is directed between the portal and the identification tag and the interrogation system is reset to isolate and identify any remaining tags.

  • Patent number: 5233347
    Abstract: An apparatus suitable for implementation in synchronous manufacturing systems includes operator stations, a request panel and an acknowledge panel. The operator stations are coupled to the request panel and send request signals to the request panel. The request panel converts the request signals from the operator stations to serial data and transmits that data in a data burst to the acknowledge panel at a remote location in the plant. The acknowledge panel signals the data requests to an operator at the acknowledge panel. Push buttons at the acknowledge panel provide acknowledge signals to the acknowledge panel, which converts the acknowledge signals to serial data and transmits that data in a data burst to the request panel. The request panel transmits the data it receives to the operator stations.

  • Patent number: 5198799
    Abstract: A surveillance fence comprising at least two posts (10) each equipped with electro-magnetic radiation transmitters (12) and receivers (14) which establish two parallel communications links. Each posts (10) communicate with a surveillance computer at a headquarters (20). Only one post (10) communicates directly via cables with headquarters (20). Data is transmitted over the communication links in opposite directions by modulating the electromagnetic energy beams. A message starts at headquarters (20) and is passed along post (10) to post (10) and back again to headquarters (20). Each post (10) can add information to the message as it is passed along. The interruption of the electromagnetic energy beams signals an intrusion whose location and time of occurence is recorded by a processor (16) which initiates an alarm. If a post (10) can not relay its intrusion data, the data is stored until the communications link is reestablished.
